Study Summary

The purpose of the present pilot study is to test the hypothesis that in patients with group 1 pulmonary arterial hypertension (PAH) who are on regular oral pulmonary vasodilator therapy, inhaled albuterol causes transient pulmonary vasodilation.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • A Mean Pulmonary Artery Pressure >25mmHg, Pulmonary Vascular Resistance >3 wood/unitsand pulmonary arterial wedge pressure <15mmHg, as documented by right heartcatheterization within the last 3 years
  • Regular use of oral pulmonary vasodilators

Exclusion

Exclusion Criteria:

  • Presence of chronic respiratory disease (as documented by prior lung imaging andpulmonary function tests), cardiovascular disease (as documented by priorechocardiography and/or left heart catheterization), thromboembolic PAH (as documentedby pulmonary angiography)
  • women of childbearing potential who do not use accepted birth- control measures
  • pregnant and breast-feeding women
  • respiratory infection within 4 weeks of testing
  • A systemic systolic arterial BP> 150 and/or diastolic arterial BP>100 on theexperiment day
  • A resting O2 saturation of < 90%
  • Current smoking
  • BMI >35 kg/m2 and/or a diagnosis of obstructive sleep apnea
  • Use of inhaled or intravenous pulmonary vasodilators
